1 Laws of Motion
A coin is dropped in a lift. It takes time t1 to reach the floor when lift is stationary. It takes time t2 when lift is moving up with constant acceleration. Then 1) t1 > t2 2) t2 > t1 3) t1 = t2 4) t1 >> t2
SOLUTION:
For stationary lift
and when the lift is moving up with constant acceleration
∴ t1 > t2
